Gemstone Caverns

Legendary Land

If Gemstone Caverns is in your opening hand and you're not playing first, you may begin the game with Gemstone Caverns in play with a luck counter on it. If you do, remove a card in your hand from the game.

Tap: Add (1) to your mana pool. If Gemstone Caverns has a luck counter on it, instead add one mana of any color to your mana pool.

For Tainted Pact , there are enough Swamp substitutes. Instead of 9 Swamps and 1 Urborg, Tomb of Yawgmoth, you can run the following:
1x Swamp
1x Snow-Covered Swamp
1x Cabal Pit
1x Ifnir Deadlands
1x Shizo, Death's Storehouse
1x Tomb of Urami
1x Urborg
1x Urborg, Tomb of Yawgmoth
1x Vault of Whispers
1x Gemstone Caverns or Gemstone Mine

Of course, most of these are worse than swamps, but they turn Tainted Pact on

Here are my thoughts, in no particular order

Your land base is just 1 card away from running Tainted Pact for use with Labman lines. You should ditch that 2x island and run it. Also run the new Jace as a back up.

Omniscience + Show and Tell should be cut. Replace with Dramatic Reversal + Isochron Scepter . Its a more compact win, doesn't have the opportunity to blow up in your face, combos with Top and Copy Artifact, and both pieces have higher quality than the pieces they are replacing.

You run a lot of large CMC junk cards that will either end as dead draws or don't win upon resolving. Consecrated Sphinx should be put into play with reanimation, but since you don't run you should cut. Bolas's Citadel is just a bad Ad Nauseum. The handful of wheel cards over 3 CMC should be cut. Why spend that time giving your opponents cards on a soft combo when you could be tutoring and winning with the very easy A + B of Labman + pact? Specifically, Time Spiral Wheel and Deal Reforge the Soul Whispering Madness . Replace those cards with more format staple counterspells and removal. Swan Song Dispel Flusterstorm Red Elemental Blast Abrade Shattering Spree .

Really not wild about Molten Psyche or Winds of Change either. You are losing card advantage on both (-1 to be precise). Notion Thief and Waste Not are both strong when used with a wheel, but it isn't worth devoting that many deck slots to combos that don't explicitly win. You would be better off running tutors instead, which will help you get whichever A or B part of the Notion Wheel combo you don't have in your hand.

You really don't need to run Mission Briefing if you are running Snapcaster AND yawgill AND past in flames.

You should highly consider Chain of Vapor as well as Hurkyl's Recall . Both allow you to gain mana and storm when combined with the mana positive rocks, which feeds into your Aetherflux Reservoir line. They also double as removal and can combo break opponents who are trying to win.

You should include Mana Vault , its much better than Basalt Monolith . Thought Vessel should also be cut, even Prismatic Lens is better. The no maximum hand size will literally never be relevant, because if you are drawing that many cards you should be able to win instead of passing the turn. If you do have to discard down to 7, just keep the 7 that allow you to win and protect the win. You should also run Chrome Mox because of the high card advantage you generate.

28 lands means you're in danger of getting staxed out, very easily. Any artifact hate with early taxes means you're caught and discarding cards for multiple turns. The land base you're running could also use a tune up. You should include the painlands Underground River etc. as they enter untapped and provide color diversity without extra requirements. The two-or-more-opponents lands I'm not a fan of, but playing in a pod means they'll be live. The two-or-fewer-lands lands I'm not a fan of, and firmly believe you should cut. Checklands are fine, but replaceable long term. You should also run more rainbowlands, specifically Forbidden Orchard Gemstone Caverns Tarnished Citadel . If you are running Tolaria West as a 0 drop tutor, don't count it as a land towards your total, if you're running it as an island, it comes out tapped so cut it.

You should get a creature sweeper. Earthquake is great and can double as a wincon if you're above opponents in life, also ignores Kess. Pyroclasm clears opposing mana dorks for very cheap.

Your cantrips are a bit goofy too. Thought Scour should be replaced with Sleight of Hand , which gives you more flexibility about the card you get as well as gets around draw restrictions such as Alms Collector or Spirit of the Labyrinth . Fact or Fiction is simply too much CMC. I'm personally not a fan of Scroll Rack but that's entirely your call.

Terminate should be Pongify or Rapid Hybridization . Its 1 cmc cheaper and less color intensive, and if you lose to a 3/3 token you were going to lose anyways. Notably, Kess can kill the token by blocking.

A green splash for Cryptolith Rite and Ancient Stirrings offers a lot, and allows you to play a backup combo with similar pieces- Training Grounds / Biomancer's Familiar with Umbral Mantle /manland and similar 'untap for effect' cards mean you can run a lot of redundant pieces- Gilder Bairn /any counter, Pili-Pala for infinite mana, etc.

You basically have two ways to make it happen-

Counterspells/protection so you can untap with puresight merrow (where I'd consider Lightning Greaves worth testing). I'd look at Gemstone Caverns and ornithopter for mantle, since going off a turn earlier will let you dodge a lot of removal, then counter backup- spell pierces and negates primarily.

The other option so many redundant combo pieces that your opponent runs out of answers. This will likely call for your interaction to be able to stop them winning- so mana leak and friends, backed by lots of cheap 'I might win with this next turn' cards.

The best deck likely sits somewhere between both extremes, so use judgement and have fun.

Yeah, I didn't want to be impolite, but there are so many glaring issues, that I am inclined to believe he hasn't actually played in a cEDH table.

I tinkered with Azusa for like a year and a half and one Gilded Drake or Phantasmal Image was usually enough to ruin the whole game for the table since blue player inturn gets Azusa in a deck better equipped to make use of 3 land drops a turn.

You're also missing: Carpet of Flowers (always in the main) Mox Diamond Chrome Mox Utopia Sprawl Wild Growth Gemstone Caverns Beast Within (why?...you're already neutered in this color)

One Root Maze and you're out of the game. Some deck can literally outpace you and the whole purpose of Azusa is to race... If you lose that race you always lose. How do you kill without combat? How do you remove anything?

Alright lets break down your deck and take a peak.

Lands

Nothing too crazy with your land base. I'm not wild about the "two or fewer" lands, or the "two or more opponents" lands, but they work inside an EDH pod. Two or fewer is worse in my opinion. Forbidden Orchard is a card you should definitely consider, Gemstone Caverns as well. River of Tears is not reliable and I'm not a fan. Obviously the original Duals will serve you well here, but those are $$$.

Looks like your land base is trying to run High Tide as well as Tainted Pact . Those cards unfortunately aren't compatible, so you need to choose one package. I think Tainted Pact is a better choice because its a neat A + B with Laboratory Maniac , whereas you don't have a guaranteed outlet for all that High Tide mana. Consider trimming down to just 1x of all your lands, look at one time rainbow lands if you need budget Aether Hub Tendo Ice Bridge .

Wincons

Simply put, you have too many win cons. Turn the slots from the weaker ones into support for your stronger ones.

Wanderwine Prophets is expensive to cast. It also requires combat damage to a player, meaning your combo is only live as long as you can swing freely. Regardless, its still a strong way to close games. You need to run proper support for reanimating. First, you need to increase reanimation density. Necromancy Apprentice Necromancer Exhume Shallow Grave . Next, you need to ensure you can get your reanimation targets to the graveyard. Careful Study is probably the only one I'd add, although there are certainly more options. Finally, it helps to have extra reanimation payloads in case Wanderwine is unavailable. Jin-Gitaxias, Core Augur and Consecrated Sphinx are both strong enough to cause you to run away with games from card advantage, most likely guaranteeing a win.

Next, Tainted Pact / Demonic Consultation + Laboratory Maniac . I think this is the strongest win condition you're currently running. Important that you pack density of "draw a card" effects to guarantee same turn winning. Make sure to optimize your land base so Tainted Pact is a guarantee!

Mind Over Matter + Azami, Lady of Scrolls is your weakest combo. Its needlessly expensive at 11 mana! The pieces are also the hardest to cast and tutor. The 4 blue in MoM makes it prohibitive sometimes, same with the 3 in Azami. The pieces are also found by the fewest amount of tutors you run, while the tainted pact combo is far more easily searchable.

Doomsday is strong but you are lacking some necessary cards. Gush and Gitaxian Probe will make your life far easier. Same with Lion's Eye Diamond . I would currently cut this from your deck.

Dualcaster Mage / Naru Meha, Master Wizard + Ghostly Flicker / Illusionist's Stratagem is also relatively weak. Requires you to hold then dump all the mana during the same turn, and 6-8 mana is not a fantastic range. The cards are also rather weak outside the combo, but not horrible. You can add additional value by getting more ETB creatures or blink effects for combo. Twinflame Heat Shimmer Cackling Counterpart Imperial Recruiter

Ramp

Looks like you know what you're missing as far as moxen goes. You should also consider running the Signet cards, gives reliable ramp that avoids land hate. Also adds artifact density for when you get that Mox Opal . Wayfarer's Bauble is bad and should be cut.

Card Draw

You are lacking some card draw that would help you. Dark Confidant Mystic Remora Rhystic Study . Sensei's Divining Top works extremely well with fetchlands and would provide value here. Top would also allow value wincons to be inserted like Dramatic Scepter or Paradox Engine . Kess, Dissident Mage gives massive value here and helps you escape from grindy mid games against other control decks. Wheel of Fortune and Timetwister will obviously help here, but are $$$. Windfall is extremely strong as it neutralizes opponents who get massive card advantage early in the game, or helps you after you dump a fast hand.

Interaction and Removal

Pyroblast is worse than REB and you shouldn't run it. 13 counterspells is certainly too high, you can also cut another. You currently run three spells that can deal with a resolved enchantment, Chain of Vapor Galecaster Colossus and Venser, Shaper Savant . A Rule of Law or Arcane Laboratory that has resolved ends your game. Galecaster is pretty low value and should be removed. Dismember both hits for a lot off of Ad Naus and costs a lot on your Ad Naus to be low costed to cast. You should swap it out for a sweeper like Pyroclasm or Earthquake , you already have strong targeted removal. Abrade is the exception, and should be added due to its flexibility.

Closing Thoughts

You are definitely on the right track. Cast a critical eye towards anything 3+ CMC, as those greatly rob your Ad naus and are harder to cast. Archaeomancer and Galecaster Colossus specifically stand out as removes. Test out a few different Grixis flavored wincons and see which one feels the best based on the paper cards you have. Take a peek at Kiki Jiki + friends, as well as Isochron Scepter + Dramatic Reversal . Kiki fits into reanimator, and dramatic scepter is extremely easy to slot and assemble. Test out Dualcaster/Meha with additional combo payoffs, because there are quite a few that let them combo off. Your deck is currently at a point where you need to start greatly considering card quality and slot intensiveness. The fewer slots, the easier to cast, the more the pieces have value alone outside the combo, the better. You also need to start considering the hate pieces other decks are going to run. How do you handle Torpor Orb for example?

Going to try Ghost Quarter in place of Gemstone Caverns . The ramp was nice when I actually got to do it, but not being able to tap for colorless when it has a luck counter really hurts.

It'd be no fun to just include Standard legal cards, so lets just go Modern.

The first thing that would 100% happen is MonoDross. 60x Chancellor of the Dross .

Everything else would run Providence to survive it. Then they'd probably run alot of Chancellor of the Forge and Memnite or some sort of combo with Chancellor of the Tangle , Gemstone Caverns , and Simian Spirit Guide . Maybe Midnight Guard / Presence of Gond as a t2 Splinter Twin w/out haste?

One big problem is the fact that MonoDross Mirror matches would just be like "Lololol neither of us can win we both at 21 let's see who concedes first" or it would be whoever goes first wins bc the other person nat mills first.

What say you?
